Annual Meeting 2011 The Palaeontological Association 55th Annual Meeting 17th–20th December 2011 Plymouth University PROGRAMME and ABSTRACTS Palaeontological Association 2 ANNUAL MEETING ANNUAL MEETING Palaeontological Association 1 The Palaeontological Association 55th Annual Meeting 17th–20th December 2011 School of Geography, Earth and Environmental Sciences, Plymouth University The programme and abstracts for the 55th Annual Meeting of the Palaeontological Association are outlined after the following summary of the meeting. Venue The meeting will take place on the campus of Plymouth University. Directions to the University and a campus map can be found at <http://www.plymouth.ac.uk/location>. The opening symposium and the main oral sessions will be held in the Sherwell Centre, located on North Hill, on the east side of campus. Accommodation Delegates need to make their own arrangements for accommodation. Plymouth has a large number of hotels, guesthouses and hostels at a variety of prices, most of which are within ~1km of the University campus (hotels with PL1 or PL4 postcodes are closest). More information on these can be found through the usual channels, and a useful starting point is the website <http://www.visitplymouth.co.uk/site/where-to-stay>. In addition, we have organised discount rates at the Jury’s Inn, Exeter Street, which is located ~500m from the conference venue. A maximum of 100 rooms have been reserved, and will be allocated on a first-come-first-served basis. Further information can be found on the Association’s website. Travel Transport into Plymouth can be achieved via a variety of means. Travel by train from London Paddington to Plymouth takes between three and four hours depending on the time of day and the number of stops. The lowest fares are available by booking in advance, e.g. through the First Great Western website (<www.firstgreatwestern.co.uk>). Flights to and from Plymouth airport have, unfortunately, recently been suspended, but many national and international airlines fly into Exeter airport or Newquay airport. Of the two, Exeter has the best public transport links to Plymouth and is one hour away from Plymouth by train. Ferries link Plymouth to France (Roscoff), Spain (Santander), and Cornwall. National Express coaches link Plymouth with all major UK cities and Palaeontological Association 2 ANNUAL MEETING London airports. Plymouth University is situated a few minutes’ walk from the train station, coach/ bus station, and a number of hotels, guesthouses and other accommodation. Delegates arriving by car are advised that the nearest public car parks are in Regent Street and in Drake Circus shopping centre. There will be limited free parking spaces on campus on Saturday and Sunday only. Blue badge holders will receive priority and should contact Sally Bishop-Hawes by e-mail to <[email protected]> to secure a place. Registration at the conference Registration will take place in the foyer of the Sherwell Centre, and will be open from 12.00 to 17.30 on Saturday 17th December, and from 08.00 to 17.00 on Sunday 18th December. Symposium The opening symposium on ‘Ancient and modern biotic crises’ will take place in the Sherwell Centre beginning at 13.45pm on Saturday 17th December. Icebreaker Reception This will commence at 18.15, following the symposium, and will take place in the Council Houses, Armada Way, PL1 2AA, located in the town centre, a 10-15 minute walk from campus. Transport will be provided for those who need it. Oral and poster sessions All oral presentations will take place in the Sherwell Centre, on the campus of the University. Single sessions will be held in the Lower Lecture Theatre, whereas the parallel sessions will utilise both Upper and Lower lecture theatres as indicated in the programme. The posters will be available for viewing throughout the conference in the Main Hall, where lunch will also be served on Sunday and Monday. There will be a dedicated poster session from 09.00–10.30 on Monday 19th December. Each poster will be assigned a single poster board and volunteers will be present in the Main Hall to assist contributors in putting up their posters. Each poster board is approximately 1.8m high by 0.9m wide. Annual Address The annual address will be given at 17.15 on Sunday 18th December by Professor Paul Pearson, on ‘Climate and evolution in the Cenozoic oceans’. This will be held in the Lower Lecture Theatre of the Sherwell Centre. Drinks Reception & Annual Dinner There will be a drinks reception followed by the Annual Dinner in the Guildhall on Sunday 18th December. The drinks reception will commence at 19.00 and the dinner at 20.00. The Guildhall is located at the junction of Armada Way and Royal Parade, in the town centre, a 10-15 minute walk from campus. Transport will be provided for those who need it. Some free parking is available at the venue. ANNUAL MEETING Palaeontological Association 3 Field excursion The field excursion will leave from the North Hill entrance to campus, between the Sherwell Centre and the Main Hall, at 9.00am on the morning of Tuesday 20th December. The itinerary will include examination of some of the famous, fossiliferous marine Devonian localities of the Torquay area (the English Riviera Global Geopark) in the morning, followed by lunch and an afternoon tour of Kents Cavern. At the end of the day, delegates will have the choice of returning to Plymouth or of being dropped off at Newton Abbott train station, which is on the main line to Exeter and all stations north and east. Further details will be provided to those who have registered for the fieldtrip after the final registration deadline of 18th November.

SAUL Invertebrate Paleontology Section, Natural History Museum of Los Angeles County, 900 Exposition Boulevard, Los Angeles, California 90007, USA Abstract. The Cretaceous record of the nuculid bivalve Acila (Truncacila) Grant & Gale, 1931, is established for the first time in the region extending from the Queen Charlotte Islands, British Columbia, southward to Baja California, Mexico. Its record is represented by three previously named species, three new species, and one possible new species. The previously named species are reviewed and refined. The cumulative geologic range of all these species is Early Cretaceous (late Aptian) to Late Cretaceous (early late Maastrichtian), with the highest diversity (four species) occurring in the latest Campanian to early Maastrichtian. Acila (T.) allisoni, sp. nov., known only from upper Aptian strata of northern Baja California, Mexico, is one of the earliest confirmed records of this subgenus. ‘‘Aptian’’ reports of Trun- cacila in Tunisia, Morocco, and possibly eastern Venzeula need confirmation. Specimens of the study area Acila are most abundant in sandy, shallow-marine deposits that accumulated under warm- water conditions. Possible deeper water occurrences need critical evaluation.

  • Functional Morphology and Evolu Tion of Xiphosurids
    Func tional morphol ogy and evolu tion of xiphosurids JAN BERGSTROM Bergstrom, J. 1 975 07 15: Functional morphology and evolution of xiphosurids. Fossils and Strata, No. 4, pp. 291-305, Pl. 1. Oslo. ISSN 0300-9491. ISBN 82-00-04963-9. Aspects of the morphology, evolution and systematics of the Xiphosurida are treated. The ancestrai forms lacked specialization for ploughing, and their chilaria were evidently developed as prosomal walking legs. The cor­ responding tergite (of the pregenital segment) was probably separate from the main prosomal shield in the early xiphosurids as well as in the eurypter­ ids. From this stem two main groups seem to have evolved. One consists of the synziphosurids, large-eyed eurypterid-like hunters with stri king opistho­ somal tagmosis. The other consists of the burrowing and ploughing xipho­ surids, in which the opisthosomal tergites were subject to progressive fusion ending with a single opisthothoracic tergal shield in the Late Palaeo­ zoic. The last prosomal appendages evolved into the chilaria, if this did not happen earlier, and the corresponding free tergite disappeared. Probably in Carboniferous time the limulines came into existence through a sudden displacement of the prosomal/opisthosomal boundary. Jan Bergstram, Department of His torical Geology and Palaeontology, Un iversity of Lund, Solvegatan 13, S-223 62 Lund, 1st August 1973. The Xiphosura may be considered to constitute a subdass or dass of chelicerate arthropods. The delimitation has been diseussed in the past, but no general agreement seems to exist. Generally, the xiphosurids are induded with the aglaspidids and eurypterids in the Merostorna­ ta. However, as generally understood, this taxon probably represents an evolutionary grade rather than a phylogenetic unit.

CENTRAL AMERICAN PROVINCIALISM AND THE GREAT AMERICAN BIOTIC INTERCHANGE Michael O. Woodburne1,* Alberto L. Cione2,**, and Eduardo P. Tonni2,*** ABSTRACT The age and phyletic context of mammals that dispersed between North and South America during the past 9 m.y. is summarized. The presence of a Central American province of cladogenesis and faunal differentiation is explored. One apparent aspect of such a province is to delay dispersals of some taxa northward from Mexico into the continental United States, largely during the Blancan. Examples are recognized among the various xenar- thrans, and cervid artiodactyls. Whereas the concept of a Central American province has been mentioned in past investigations it is upgraded here. Paratoceras (protoceratid artio- dactyl) and rhynchotheriine proboscideans provide perhaps the most compelling examples of Central American cladogenesis (late Arikareean to early Barstovian and Hemphillian to Rancholabrean, respectively), but this category includes Hemphillian sigmodontine rodents, and perhaps a variety of carnivores and ungulates from Honduras in the medial Miocene, as well as peccaries and equids from Mexico. For South America, Mexican canids and hy- drochoerid rodents may have had an earlier development in Mexico. Remarkably, the first South American immigrants to Mexico (after the Miocene heralds; the xenarthrans Plaina and Glossotherium) apparently dispersed northward at the same time as the first Holarctic taxa dispersed to South America (sigmodontine rodents and the tayassuid artiodactyls).

  • Early Ontogeny of Jurassic Bakevelliids and Their Bearing on Bivalve Evolution
    Early ontogeny of Jurassic bakevelliids and their bearing on bivalve evolution NIKOLAUS MALCHUS Malchus, N. 2004. Early ontogeny of Jurassic bakevelliids and their bearing on bivalve evolution. Acta Palaeontologica Polonica 49 (1): 85–110. Larval and earliest postlarval shells of Jurassic Bakevelliidae are described for the first time and some complementary data are given concerning larval shells of oysters and pinnids. Two new larval shell characters, a posterodorsal outlet and shell septum are described. The outlet is homologous to the posterodorsal notch of oysters and posterodorsal ridge of arcoids. It probably reflects the presence of the soft anatomical character post−anal tuft, which, among Pteriomorphia, was only known from oysters. A shell septum was so far only known from Cassianellidae, Lithiotidae, and the bakevelliid Kobayashites. A review of early ontogenetic shell characters strongly suggests a basal dichotomy within the Pterio− morphia separating taxa with opisthogyrate larval shells, such as most (or all?) Praecardioida, Pinnoida, Pterioida (Bakevelliidae, Cassianellidae, all living Pterioidea), and Ostreoida from all other groups. The Pinnidae appear to be closely related to the Pterioida, and the Bakevelliidae belong to the stem line of the Cassianellidae, Lithiotidae, Pterioidea, and Ostreoidea. The latter two superfamilies comprise a well constrained clade. These interpretations are con− sistent with recent phylogenetic hypotheses based on palaeontological and genetic (18S and 28S mtDNA) data. A more detailed phylogeny is hampered by the fact that many larval shell characters are rather ancient plesiomorphies. Key words: Bivalvia, Pteriomorphia, Bakevelliidae, larval shell, ontogeny, phylogeny.

    ACTA PALAEONT OLOGICA POLONICA Vol. VII 1 9 6 2 N os. 1-2 L. BEVERLY TARLO THE CLASSIFICATION AND EVOLUTION OF THE HETEROSTRACI Abstract. - An outline classification is given of the Hetero straci, with diagnoses . of th e following orders and suborders: Astraspidiformes, Eriptychiiformes, Cya­ thaspidiformes (Cyathaspidida, Poraspidida, Ctenaspidida), Psammosteiformes (Tes­ seraspidida, Psarnmosteida) , Traquairaspidiformes, Pteraspidiformes (Pte ras pidida, Doryaspidida), Cardipeltiformes and Amphiaspidiformes (Amphiaspidida, Hiber­ naspidida, Eglonaspidida). It is show n that the various orders fall into four m ain evolutionary lineages ~ cyathaspid, psammosteid, pteraspid and amphiaspid, and these are traced from primitive te ssellated forms. A tentative phylogeny is pro­ posed and alternatives are discussed. INTRODUCTION Since 1858, when Huxley demonstrated that in the histological struc­ ture of their dermal bone Cephalaspis and Pteraspis were quite different from one another, it has been recognized that there were two distinct groups of ostracoderms for which Lankester (1868-70) proposed the names Osteostraci and Heterostraci respectively. Although these groups are generally considered to be related to on e another, Lankester belie­ ved that "the Heterostraci are at present associated with the Osteostraci because they are found in the same beds, because they have, like Cepha­ laspis, a large head shield, and because there is nothing else with which to associate them". In 1889, Cop e united these two groups in the Ostracodermi which, together with the modern cyclostomes, he placed in the Class Agnatha, and although this proposal was at first opposed by Traquair (1899) and Woodward (1891b), subsequent work has shown that it was correct as both the Osteostraci and the Heterostraci were agnathous.

  • The Extent of the Sirius Passet Lagerstätte (Early Cambrian) of North Greenland
    The extent of the Sirius Passet Lagerstätte (early Cambrian) of North Greenland JOHN S. PEEL & JON R. INESON Ancillary localities for the Sirius Passet biota (early Cambrian; Cambrian Series 2, Stage 3) are described from the im- mediate vicinity of the main locality on the southern side of Sirius Passet, north-western Peary Land, central North Greenland, where slope mudstones of the Transitional Buen Formation abut against the margin of the Portfjeld Forma- tion carbonate platform. Whilst this geological relationship may extend over more than 500 km east–west across North Greenland, known exposures of the sediments yielding the lagerstätte are restricted to a 1 km long window at the south-western end of Sirius Passet. • Keywords: Early Cambrian, Greenland, lagerstätte.

    A new arthropod from the lower Cambrian Sirius Passet Fossil-Lagerstätte of North Greenland JOHN S. PEEL & MARTIN STEIN Aaveqaspis inesoni gen. et sp. nov., is described from the lower Cambrian Sirius Passet Fossil-Lagerstätte of Peary Land, North Greenland. It has a semicircular head shield and a thorax with 5 tergites. The tail shield carries 2 pairs of spines, the most anterior of which is enormous and dominates the trunk. A. inesoni lacks any preserved trace of eyes, as is also the case with several other Sirius Passet arthropods, suggesting that the fossils accumulated in deeper water than the contemporaneous Chengjiang Fossil-Lagerstätte of China or the middle Cambrian Burgess Shale assemblages of British Columbia. • Key words: Cambrian, arthropod, Sirius Passet, Lagerstätte, Greenland.
